StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 16 August 2026; the live site may have changed since.

Jiankun still has work before launch. What needs work: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Hacker News on August 16, 2026. The site is served through Cloudflare. The crawl picked up 5 technologies on this site, covering business email, analytics, CDN, and DNS providers. The stack includes Bluehost Email, Cloudflare, and Cloudflare DNS.
